The investigations of both parties have made progress at the same time, which should be a gratifying thing.
But the double progress did not bring double the excitement, but instead endless emptiness.
Because both the sodium carbonate found by Karasawa and the alibi about Yamamura Kage found by Gong Chang Criminal pointed the prisoner to a prisoner with professional knowledge.
It is equivalent to saying that after Karasawa interrogated Yamamura Kage, he judged that the other party was telling the truth and that he was not a prisoner. This inference was confirmed.
Although this guy is a potential prisoner, he is not a prisoner.
Of course, although you cannot arrest the other party because he has dangerous ideas, you still need to follow up.
After Tang Ze exchanged information with the other party, he reminded Gong Chang from the police department to send someone to pay more attention to the other party, and then hung up the phone.
??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? What are we going to do next?¡±
Seeing Karasawa finish the phone call, Takagi said with some distress: "Although we know that the ignition point was caused by a substance containing sodium carbonate, there is a high possibility that the suspect is also a professional.
But there are too many qualified candidates, and we simply don¡¯t know where to start now. "
"The suspects can be eliminated slowly. For now, let's start with channels."
Tangze thought for a while and said: "After all, even if the fire is caused by sodium carbonate, all the substances in it cannot be the same.
If we can find the same fire object as the sample collected, then the channel will be determined, which should be able to narrow the scope to a certain extent. "
"Sodium carbonate is not something that is easy to get, right?" Takagi suddenly said after hearing this: "It is indeed a good way to start from this aspect."
"In fact, it is very simple for professionals. As long as there is a certain acid and glycerin, nitroglycerin can be produced."
"For example, 50% of the ingredients in enemas are glycerin, which can be easily purchased," Karasawa said.
We will go to the drugstore later, buy all the enemas on the market, and then compare them with the sodium carbonate in our hands through experiments.
As for acid, which is not something that is easy to obtain, it seems that it is what the prisoners have on hand. We can just use several common acids instead. "
"So, you still need to trouble Mr. Saito?"
Hearing this, Takagi looked at Tang Ze and said, "You just said you would let him rest. Are you already planning to let him take over this huge workload?"
"That's not true." Tang Ze waved his hand and said, "Just leave such a simple comparison task to your subordinates. Let's go and buy an enema first."
After traveling around Tokyo with the money and buying all the brands of enemas, the two returned to Kesouyan and started squeezing the labor force of their employees.
Fortunately, the current operation of the Science Search and Research Institute is good, advanced technology also provides good logistical services to the Metropolitan Police Department, and personnel are recruited again and again.
Coupled with the fact that Tang Ze, the immediate boss, personally assigned the task, the efficiency is still very high.
The exhaustive method, combined with the human sea tactics, quickly yielded results, but what was disappointing was that the various combustion residues they tested were completely different from the fire scene.
Although sodium carbonate is indeed generated, other trace impurities are completely different.
These trace impurities are equivalent to a "fingerprint". Only when the same substances are fused and burned will basically the same magazine be obtained.
The absence of this impurity means that the prisoner did not use these things to make nitroglycerin.
"Does that mean it wasn't nitroglycerin that started the fire?" Takagi said with some disappointment after receiving the results of this large-scale experiment.
"No, the general direction is correct."
Tang Ze shook his head and said: "But we don't know the specific manufacturing materials yet. This is a good thing and a bad thing."
The good thing is that the prisoner used special materials to make nitroglycerin. If it can be found, the prisoner can be directly targeted.
But the bad news is that it¡¯s like looking for a needle in a haystack. If you can¡¯t find the special material, there¡¯s no way to start.
As expected, even if Karasawa finally brought Hiroshi Saito to think about it, he still didn¡¯t realize what special materials the prisoner used to synthesize nitroglycerin.
And this kind of thing should be very common.
For example, a chemistry teacher, although it is indeed easy to come into contact with the ability to synthesize nitroglycerinHe was gesticulating with something.
"I'm eating, why did you get up?"
Karasawa looked at Ayako who seemed to be choosing a place to visit the flower pot and said in surprise: "Also, what are you doing with that pot of flowers?"
"Eh? Isn't this given to you by your friend?"
Hearing what Karasawa said, Ayako held the flowers with a surprised look on her face: "You got this back after drinking yesterday. I thought your friend gave it to you when you went to a friend's house for dinner."
"Ah, I forgot to mention it in the excitement yesterday." Karasawa patted his forehead and told Ayako what happened yesterday.
"It turns out it was given to Sato Criminal. She gave it to you so you could reject Mr. Samejima."
Ayako looked at the flowers in her hands with some regret: "I raised such beautiful flowers, but it's a pity that I didn't give them to the owner.
? It can be seen that Mr. Samejima is fertilizing and watering the flowers very carefully. "
"etc."
Karasawa stopped what he was doing and suddenly turned his head to look at Ayako: "What did you just say!?"
"Eh?" Ayako subconsciously repeated after seeing Karasawa's words: "I said such a beautiful flower"
"It's not this sentence." Karasawa interrupted Ayako, "It's the next sentence."
"I said Mr. Samejima is very attentive in fertilizing and watering the flowers." Seeing Karasawa's dazed look, Ayako didn't have any strange look on her face. Instead, she cooperated and repeated her words. Again.
¡°After all, for her, having a husband who is a criminal is like this. Occasionally, she will remind the other party by inadvertent words.
If you guessed correctly, the other party will be thanked by the other party for his meritorious service later.
And as soon as this thought came to an end, Ayako felt her whole body being hugged.
"Thank you so much, you are my lucky star." Tangze kissed Ayako on the cheek: "You have done a great job!"
"As long as I can help you." Ayako looked at Karasawa's excited look and smiled: "As a thank you, please solve the case quickly and take a vacation."强牺 ti&# 97nlaixsw.com 读牺
"Okay." Tang Ze just finished nodding, his nose moved slightly and he looked at the crab shell with crab roe sitting on the side, and his expression changed: "Oh no, the crab roe has been roasted."
After hurriedly rescuing the crab roe, Tangze tasted it and breathed a sigh of relief.
Fortunately, it was just a little baked, a little bit of bitterness, and it was not scrapped.
After adding some seaweed and sesame seeds to the rice, Karasawa tasted it and breathed a sigh of relief.
Fortunately, it is slightly bitter but has a different flavor, which is not bad.
He fed Ayako two mouthfuls with a spoon to give her a taste, and Karasawa wiped the rest away.
After dinner, the two went out to watch an opera, and then returned home leisurely.
Although Karasawa came up with a breakthrough clue through Ayako's inadvertent reminder, Karasawa was not so angry that he even ignored his life and plunged into work.
And this verification also requires a huge workload, and it won¡¯t be done in a hurry. At this time tian l*aixsw.com Zhang Si
The next morning, Tang Ze did not go to work early. Instead, he rested at home after eating and did not go out until eight o'clock.
¡°And his destination is not the Metropolitan Police Department, but the largest fertilizer store in Tokyo.
Yes, Ayako¡¯s words yesterday reminded him of an important piece of information, or helped him get out of his misunderstanding.
Glycerin can be easily obtained in enema. Although simple "acid" is not so easy to obtain, some things come with "acid", which can still achieve the same effect.
And gardening fertilizers are the most common substances that may contain the element "acid".
With a wave of his hand, Tangze bought all the fertilizers on the market and asked people to put the things in the trunk of his bicycle.
Fortunately, although there are a lot of fertilizers, they are all in small packages, and a package can be put in Tang Ze's trunk. Otherwise, he would have to hire someone to drive a truck to send it to scientific research.
However, when he came to the laboratory department carrying a large amount of fertilizer, he still caused a cry.
After all, the previous workload was enough to devastate them, but they didn¡¯t expect to have to do it all over again this time, with an even greater workload.
After all, this time we mixed fertilizer and enema together to see if it matched the magazine at the crime scene.
Just thinking about that huge combination makes everyone¡¯s scalp numb.
"Okay, I know the workload is heavy this time, so I'll give you overtime pay."
Tang Ze hugged the pot of flowers and said with a smile: "Thank you for your hard work. Now go to my car to bring up the fertilizer, and buy some food and drink. I'll treat you." Zhida z.com Zhixiao
Hearing Tang Ze¡¯s double encouragement, the faces of the researchers started to look better.
But thinking about the horrific workload, everyone still couldn't help but sigh.
And after Tangze became the hands-off shopkeeper, he increasingly felt that it was a wise choice for him to promote the establishment of "Kesouyan" at that time
